87. Achatinella juddii Baldwin. 



A.juddii Bald. P. Ac. Phila., 1895, p. 216, pi. x, figs. 3, 4. 



Shell dextral, imperforate, solid, pyramidally conical, apex 

 obtuse ; surface shining, covered with very delicate incremental 

 lines; the nuclear whorls smooth. Color light gray, shading into 

 light chestnut on the apical whorls, the gray more intense under 

 the cuticle ; with two black lines, one below and one at the 

 periphery, the latter faint and continued on the spire ; between the 

 lines a white band which revolves on the suture to the very tip of 

 the apex. Whorls 6, margined above, slightly convex ; suture 

 lightly impressed. Aperture oblique, oval, white, the light gray 

 of the exterior surface exhibiting a darker shade within ; peris- 

 tome acute, slightly thickened within, a little expanded, columellar 

 margin very slightly reflected, white, the coloring of the exterior 

 dark lines reappearing rather more intense on the inner edge ; col- 

 umella white, terminating in a moderately developed flexuous fold. 

 Length 15, diam. 91-2 mm. 



No opportunity for an examination of the animal has yet oc- 

 curred. The shell is typically very distinct from any other known 

 species. The light chestnut band on the apical whorls is a char- 

 acteristic and invariable feature. The basal portion of the shell 

 sometimes has a yellowish hue. In immature shells the colors are 

 more intense. 



Named in honor of Hon. A. F. Judd, Chief Justice of the 

 Republic of Hawaii, by whose sou the shell was discovered. — Bald. 



Hab. Halawa. — Bald.
